Toll fine with Dollar is $15 plus the sign posted toll however if theres a fault on the machine then you shouldn't get fined. I'm sure the tolling authority will have something in place which flags up that every vehicle driving through a certain toll isn't paying so they shouldn't charge you. Which road was it? might be worth dropping the toll authority a quick email with your vehicle registration to ensure no charge is sent through to Dollar.
